Abstract: The research implemented the method of highly-intensive computing applications running on the Heterogeneous multi-core DSP.Using the applications stored in the FLASH of peripheral bus of RISC core, with the Heterogeneous multi-core DSP target board power-up, automatically loaded into the RAM of RISC core and implement, the application load the Highly-intensive computing applications to the DSPs core and implement the RISC core by using DSPs cores.Introduce the reset and start method of DSP core and RISC core in the Heterogeneous multi-core DSP core, and many redundant and degraded mode of DSP core, we analyzed the principles and operation methods of the RISC core controlling DSP core in detail.This method of the article is complete and effective, and then lay a good basis for the researchers.
